Getting corruption error when processing a file for training, but file is fine

Hello,
I have installed the software under Windows, and have verified installation of all parts including

I am getting this error when clicking Process Data in the Training tab:

start preprocess
F:\Training\SRC/New MP3.mp3 -> Traceback (most recent call last):
File "D:\Apps\Python\Retrieval-based-Voice-Conversion-WebUI-main\infer\lib\audio.py", line 43, in load_audio

hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
OSError: [WinError 1392] The file or directory is corrupted and unreadable

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "D:\Apps\Python\Retrieval-based-Voice-Conversion-WebUI-main\infer\modules\train\preprocess.py", line 83, in pipeline
audio = load_audio(path, self.sr)

raise RuntimeError(f"Failed to load audio: {e}")
RuntimeError: Failed to load audio: [WinError 1392] The file or directory is corrupted and unreadable

end preprocess

I have tried proving the file in different formats, reconverting it etc. It plays just fine, so I can't see that being the issue. I've also tried other files.

I've also tried putting forward slashes to the file path etc., but it doesn't seem to help.
Your help would be much appreciated!

Thanks in advance,
Steve

Start with infer/lib/audio.py at load_audio and infer/modules/train/preprocess.py at pipeline, then reproduce Process Data on Windows using the reported path and audio file. Done means valid training audio can be processed without the reported WinError 1392 failure.
